  1. I am trying to assemble a number of png files and audio together in ffmpeg but the command lines is not recognised:

    (Could find not file with path 'pic%04d.png' and index in the range 0-4 pic%04d.png: No such file or directory)

    The cmd line used was:

    E:\upscaled\ffmpeg -r 17 -f image2 -s 2048x1152 -i pic%04d.png -vcodec libx264 -crf 17 -pix_fmt yuv420p test.mp4

    The file names start from pic000000

    I have also tried

    E:\upscaled\ffmpeg -r 17 -f image2 -s 2048x1152 -i pic%0000004d.png -vcodec libx264 -crf 17 -pix_fmt yuv420p test.mp4 with the same result, any idea where I am going wrong?

    and

    E:\upscaled\ffmpeg -start_number 000000 -r 17 -f image2 -s 2048x1152 -i pic%06d.png -i original-audio.wav -vcodec libx264 -crf 17 -pix_fmt yuv420p -acodec copy upscaled_video.mp4

  2. "pic%06d.png" for pic000000.png, pic000001.png, ....

    06 is the number of digits (six digits)

    You mention audio, but you have no audio referenced in the commandline

    Ive tried that but still get same result (Could find not file with path 'pic%06d.png' and index in the range 0-4 pic%06d.png: No such file or directory)
    I am pretty sure this should work?

    E:\upscaled\ffmpeg -r 25 -f image2 -s 2048x1152 -i pic%06d.png -i original-audio.wav -vcodec libx264 -crf 17 -pix_fmt yuv420p -acodec copy upscaled_video.mp4

    If it doesn't know the path, put the absolute path in with the png wildcard, and put that whole part in quotes.
